fix plugin showing twice?

[Omnivion]

Hi, I know you guys aren't plugin support but this is where I'd get the most relevant and fastest response. For some reason my thank you system addon shows twice. How do I fix this?

Check your postbit/postbit_classic templates for duplicated variables.

Basically what Shade means is ->

Go to Admin CP -> Templates And Styles > Templates > Theme Templates > Postbit > postbit

Find variables such as {$lang->tyl_given}(this will be duplicate) and remove them.
Check the template for more variables like this and it will be fixed

Make a backup of template before you modify.
